When the NAACP solicited UN poll watchers to inspect voting sites in the US, they wanted to hear complaints of voter suppression. Instead, UN poll watchers are baffled that the United States doesn’t require a photo ID to vote.

For the head of Libya’s national election commission, the method by which Americans vote is startling in that it depends so much on trust and the good faith of election officials and voters alike.

“It’s an incredible system,” said Nuri K. Elabbar, who traveled to the United States along with election officials from more than 60 countries to observe today’s presidential elections as part of a program run by the International Foundation for Electoral Systems (IFES). Your humble Cable guy visited polling places with some of the international officials this morning. Most of them agreed that in their countries, such an open voting system simply would not work.

“It’s very difficult to transfer this system as it is to any other country. This system is built according to trust and this trust needs a lot of procedures and a lot of education for other countries to adopt it,” Elabbar said.

The most often noted difference between American elections among the visitors was that in most U.S. states, voters need no identification. Voters can also vote by mail, sometimes online, and there’s often no way to know if one person has voted several times under different names, unlike in some Arab countries, where voters ink their fingers when casting their ballots.

The international visitors also noted that there’s no police at U.S. polling stations. In foreign countries, police at polling places are viewed as signs of security; in the United States they are sometimes seen as intimidating.
